Koualla Kakoulli, the founder of Brighton Erotic Boudoir and Dungeon in London, died on August 3, 2018. She was 56 years old. The exact cause of death remains a mystery but the local coroner refused to rule out anabolic steroids.

Kakoulli was a professional dominatrix, porn star, competitive bodybuilder and steroid user. She was best known as “Mistress Dometria” in the world of bondage and discipline, sadism and masochism (BDSM).

Brighton Coroner Veronica Hamilton-Deeley testified about the cause of death at Kakouilli’s inquest on November 21, 2018. The post-mortem examination revealed an abnormally enlarged heart. The coroner did not determine a definitive cause of death but strongly suspected steroids were a “significant contributing factor”.

Sussex Police were confident that there was no foul play involved, no signs of a struggle, no third-party involvement and no bodily trauma.

“Her death remains something of a mystery,” Hamilton-Deeley testified. “She was extremely professional in her work. She was an athlete. I cannot rule out one of the significant contributing factors was body building with the use of steroids. Many deaths are the result of a perfect storm.”

Koualla Kakoulli used anabolic steroids to compete in bodybuilding contests.

The coroner testified that Kakoulli was known to regularly use anabolic steroids especially when preparing for bodybuilding competitions. Kakoulli recently competed in international bodybuilding competitions promoted by the International Bodybuilding & Fitness Association (IFBA).

Kakoulli placed fourth in the 2017 IBFA Ms. Universe Over 50 division and third place in the 2018 IBFA Ms. Universe Over 50 division.

The pathologist report did not find any anabolic steroids at all in her system at the time of death. However, cocaine, diazepam (Valium), ketamine and mephedrone (4-MMC) were present. A white powder thought to be ketamine was discovered around her left nostril.

Mistress Dometria was well-known in the fetish community as “one of the world’s great Dominas”. The Brighton Dungeon website described her as the “world’s harshest, most hardcore BDSM Dominatrix”.
